y = -315.67x + 8986.5 T= -0.951 4,000 3,500 3,000 2,500 car insurance policy cost (dollars) 00 2,000 1,500 1,000 18 19 23 24 25 20 21 22 age (years) Twenty-one young men got a quote for the cost of a car insurance policy. The policy cost and ages of the men are shown in the scatter plot. Select all the statements that are true based on the scatter plot. The line of best fit indicates that, in general, the cost of a car insurance policy for a 21-year-old should be, on average, about $315 less than the cost of a car insurance policy for a 20-year-old. Every 19-year-old in this group has a lower cost of car insurance than the 18-year-olds. The y-intercept from the line of best fit indicates that, if the linear trend holds, a car insurance policy would be $0 for a person who is about 8,897 years old. The value of the correlation coefficient is very close to -1, so there is no association between age and car insurance policy cost. Car insurance policy cost tends to decrease as age of the driver increases.

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
